Definitions

  • the present invention relates to depilatory devices and techniques generally and more particularly to powered mechanical depilatory devices.
  • an electrically powered depilatory device including a hand held portable housing, motor apparatus disposed in the housing, and a helical spring comprising a plurality of adjacent windings arranged to be driven by the motor apparatus in rotational sliding motion relative to the skin bearing hair to be removed, the helical spring including an arcuate hair engaging portion arranged to define a convex side whereat the windings are spread apart and a concave side corresponding thereto whereat the windings are pressed together, the rotational motion of the helical spring producing continuous motion of the windings from a spread apart orientation at the convex side to a pressed together orientation at the concave side for engagement and plucking of hair from the skin, whereby the surface velocities of the windings relative to the hair greatly exceed the surface velocity of the housing relative thereto.
  • the present invention seeks to provide a mechanical depilatory device which differs from the prior art devices described above and which provides efficient and relatively painless hair removal.
  • an electrically powered depilatory device including a hand held portable housing, a hair engagement and removal assembly including elongate elements in mutually twisted engagement, and motor apparatus for driving the elongate elements in motion, whereby hair is engaged between the elongate elements and thus removed.
  • the action of the mutually twisted elongate elements when driven by the motor apparatus is to wind hair in engagement therewith.
  • the motion of the elongate elements is such that the hair is wound in engagement with the elongate elements at a location separated from the location at which it is initially engaged thereby.
  • the elongate elements form part of a single endless loop.
  • the elongate elements may be embodied in two or more separate endless loops.
  • the motor apparatus is operative to draw the elongate elements through the twisted engagement, whereby given regions of the elongate elements enter mutually twisted engagement and subsequently leave such engagement. Normally the locations at which given regions of the elongate elements enter and leave mutually twisted engagement are spaced from each other.
  • the arrangement of the elongate elements in mutually twisted engagement and the driving thereof by the motor apparatus is such that the elongate elements move forward in a generally spiral type motion and rotate about their elongate axes as they move through mutually twisted engagement.
  • the arrangement of the elongate elements in mutually twisted engagement is such that when driven by the motor apparatus, the engagement and removal assembly undergoes continuous twisting action.
  • the arrangement of the engagement and removal assembly is such that the location of the twisted engagement remains generally static relative to the housing.
  • the twisted engagement comprises multiple coils, preferably at least two in number.
  • the arrangement of the engagement and removal assembly is such that the twisted engagement extends generally linearly.
  • the twisted engagement is provided by twisting together elongate elements forming part of one or more endless loops.
  • the elongate elements are maintained in the twisted engagement by means of rollers.
  • the twisted engagement is provided by twisting together elongate elements and subsequently joining them to form one or more endless loops.
  • rollers are not needed to maintain the elongate elements in twisted engagement.
  • Figs. 1A and 1B illustrate in respective plan and sectional view, a depilatory device constructed and operative in accordance with a preferred embodiment of the invention.
  • the depilatory device comprises a hand-held portable housing 10 having formed therein a hair engagement and removal assembly 12, which is seen through an access opening 14 in housing 10.
  • the hair engagement and removal assembly 12 comprises elongate elements arranged in mutually twisted engagement, as seen at reference numeral 16.
  • the elongate elements which preferably form part of a single endless loop of flexible material, such as silicone rubber, are driven by means, not shown in Figs. 1A and 1B, examples of which are described in detail hereinbelow, so as to enter, pass through and leave mutually twisted engagement, as indicated by the arrows in Fig. 1A. It will be appreciated that motion of the elongate elements in an opposite direction to that illustrated is also possible.
  • the elongate elements may alternatively be formed of other materials such as plastics, other rubbers, and natural or synthetic fibers such as cotton.
  • the elongate elements 16 are typically twisted and then subsequently joined to define the endless loop.
  • Fig. 1C illustrates an alternative embodiment of the invention which is identical to that of Figs. 1A and 1B except that the twisted engagement comprises only a single coil.
  • the motion of the elongate elements in mutually twisted engagement as illustrated is operative to engage hair between the elongate elements and to remove such hair from the skin.
  • Two examples, which are not necessarily exclusive, of the operation of hair removal by the apparatus of Figs. 1A and 1B are illustrated in Figs. 2A - 5C, in which the thickness of the hair is exaggerated for the sake of clarity.
  • FIGS. 2A, 2B, 2C, 3A, 3B and 3C illustrate one example of hair removal action in accordance with the present invention.
  • Figs. 2A and 3A illustrate a hair about to be engaged in mutually twisted elongate elements, which are driven in the directions illustrated therein, including both motion along the elongate extent of the elements as illustrated by the arrows in Fig. 2A, and rotational motion of the elements as the enter, pass through and leave mutually twisted engagement.
  • Figs. 2B and 3B illustrate the hair being wound in engagement with the mutually twisted elongate elements, as they progress in the general direction indicated by the arrow 20 in Fig. 2B.
  • Figs. 2C and 3C illustrate the wound hair after it has been removed from its root location in the skin and has moved forward in the general direction of the arrow 20 in Fig. 2B. The removed hair disengages from the elongate elements as they leave mutually twisted engagement.
  • FIGS. 4A, 4B, 4C, 5A, 5B and 5C illustrate another example of hair removal action in accordance with the present invention.
  • Figs. 4A and 5A illustrate a hair about to be engaged in mutually twisted elongate elements, and correspond generally to Figs. 2A and 3A.
  • Figs. 4B and 5B illustrate the hair twisted together with the elongate elements, as opposed to being twisted thereover as shown in Figs. 2B and 3B.
  • Figs. 3C and 5C show the wound hair removed from the root location on the skin and displaced from the root location.
  • the actual hair removal operation of the apparatus of the invention may vary depending on a variety of conditions, including inter alia, the type and length of hair, the speed at which the elongate elements move into and through mutually twisted engagement, the location at which the hair is engaged relative to the engagement and removal assembly and relative to the root location.
  • the type and length of hair including inter alia, the speed at which the elongate elements move into and through mutually twisted engagement, the location at which the hair is engaged relative to the engagement and removal assembly and relative to the root location.
  • the hair engagement and removal assembly of the present invention is operative to remove hair by both winding it and displacing the wound hair from the root, thus resulting in double action hair removal.
  • Figs. 6A and 6B illustrate a preferred embodiment of the depilatory apparatus of the present invention. It will be appreciated that in Figs. 6A - 11, the entire hair engagement and removal assembly including the mounting and driving thereof is shown for the sake of clarity. In reality, parts of the hair engagement and removal assembly will be enclosed by the housing, as shown, for example in Fig. 1A.
  • the hair engagement and removal assembly comprises a single endless loop 30.
  • the loop is configured to define a region 32 in which the two elongate elements or portions of the loop are engaged in mutually twisted engagement.
  • a linear twisted engagement of two coils is shown. It is appreciated that alternatively non-­linear twisted engagements, as well as twisted engagements having a greater or lesser number of coils may be provided.
  • Endless loop 30 is typically mounted at four corners onto rollers 34, 36, 38 and 40, as shown, which are rotatably mounted onto housing 10.
